    The scripts have been organized based on the data they use. The main-text analyses use the CES (over-time trends, polarization) and CEMP (media) data. 
    All analyses were executed using R-4.3.2. 
    Note that the datasets for the 2008-2015 CES are loaded directly from the cesR package in the CES script.
